Title: Rotary damper
Inventor: KATSUURA NOBUO
IPC: E05F3/14
Filed: 1993-02-26
Abstract: PURPOSE:To perform the use of a rotary damper even when an installation space is limited by a method wherein a cylindrical case is rotatably held through fitting of the case in the outer peripheral part of a fixed shaft and a rotary door is engaged with the case at an engaging part arranged within a range of the thickness in an axial direction of the case. CONSTITUTION:A fixed shaft 11 is fixed to the panel of a device by means of a screw and a washer and a rotary damper 8 is mounted on the device. A protrusion piece is formed on a rotary door in the direction of the inside of the device. The protrusion piece is coupled to an arm 18 of the damper 8 through a link. Thus, the arm 18 engaged with the link is rotated according to rotation of a door, the arm 18 is slowly rotated through the brake effect of the rotary damper 8 to slowly rotate the rotary door. In this case, when a curved rack and a gear are formed to the rotary door, the rack and the gear are engaged with a gear 17 to bring it into a usable state, and by cutting the arm 18 at a root, use is facilitated.

IPC: H01L21/331
Filed: 1979-05-18
Abstract: PURPOSE:To improve dielectric strength by a method wherein on a surface of an epitaxial layer  which has reverse conduction mechanism and is on a semiconductor substrate which has a conduction mechanism and less concentration than a base layer is laminated and in a region separated by isolation layers a channel cutting layer is provided and small number of work is utilized. CONSTITUTION:An n-type buried layer 11 is formed on a p-type semiconductor substrate 10, and  an n-epitaxial layer 12 is laminated on it, and with ion implantation on it and sintering performed, a p<->-layer 13 is formed. Next thereto the epitaxial layer 14 is isolated by a p-layer, and  next thereto an n<+>-channel cutting layer 15 is formed. The n<+>-layer 15 is made to have far higher concentration than the p<->-layer 13 and depth of it is made to be deeper than the p<->-layer. Next the reto a base layer 16 and an emitter layer 17 are formed. In this process the base layer 16 is made  to be more superficial than the conventional case and is confined within the p<->-layer. By this constitution electric field concentration can not occur at the corner around the bottom in spite of  superficialness and small curvature around the bottom, and dielectric strength is improved, and  electric field concentration can not occur at the surface as a conventional case. Dielectric strength  between a base and a emitter and between an isolation region and a collector depends on the junction of layer 15 and 13.
